7770

the 7770 I bought blue screened every time i piut the monitor to sleep 3 or more times in a row.

I would research if they have fixed that driver problem before purchase.

But its certainly more powerful.

Edit: Just realised its likely the monitor that had HDCP problems that I replaced which caused this. Yeah get the 7770.
